' RING-BOOK MECHANISM.

To all whom it may concern Be it known that'I, EDWARD, VQBumrs, a citizen of the United States, and .a resident of the'city of Chicago, in the county of Cook andState of Illinois, have invented certain new and useful Improvements in Ring-Book Mechanism; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings,

and to the numerals of reference marked thereon, which form a part of this specification.

. This invention relates to an improved form of ring book mechanism adapted for use in loose leaf books and the like, em-

bracing a plurality of sets of interlocking ring sections, each set independently operable by means of suitable finger pieces or are secured upon releasably connected toggle bars mounted. on 'a resilient base plate with small leaf springs inserted between the edges of the base plate and said toggle bars, and with a slotted cover plate fitted over said acting tohold finger actuating levers in position whereby said toggle bars'may be actuated to open the rings.

It is furthermore an object of this invention to'construct a ring book wherein toggle levers are'resiliently mounted between a base and cover plate which are resiliently engaged together and with ring sections mounted on said toggle bars, so that-'when said toggle barsare sprung upwardly from the base plate by suitable actuating levers forthe purpose, said ring sections open to permit the insertion or removal of pages.

\ It is finally an object of this invention to construct a device consisting of few parts easily and cheaply manufactured, and so constructed, and arranged that the, assembly thereof is a simple operation.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described. p I v In the drawings Figure 1 is a top plan Specification of Letters Patent. Patigntmjl H43 209 i916, Application filed July 2, 1914. Serial No. 848,553.

As shown in the drawings :"My'device is associated with a looseleaf book, the covers of'gwhichfaredenotedby the reference numeral l, with the pages 2, retained therein by means of ard'evice embodying the principles of myinvention. The ring retaining ,mechanism forthe' pages embraces a curved resilient-base -plate 3, the outer convex side of which liesagaihst and is secured; to the coyer s. 1 .of the book, and the margins'of I said resillent plate are flanged inwardly toward 'one another, as denoted byjthe reference numeral 4t. Engaged within the flanged portion 4, of said, resilient base plate are wave-likeleaf springs 5, two being provided on each slde of the plate, and'each extending half the length thereof. Two sets of ring carrying toggle bars each e tendin half-the length of the base plate, ar d mount ed there1n,the-edges of the toggle bars or plates fitting into the" flangedmargins of said base plate, and bearing against the leaf springs therein. Each of the respective togglebars are provided with oflset tongues 7, .WhlCh form a hinged connection th-erebe tweenand yet donot positively connect the sametogether. Rigidly secured upon said toggleplates 6, by brazing or otherwise, are

inter-fitting substantially semi-circular. ring sections 8, and, when the toggle plates are sprung .upwardly, as shown in Fig. 5, in dotted lines,iand in full lines in Fig. 4, the

ring sections are opened away from .one

another. For the purpose of springing said toggle plates upwardly to open the rings a finger piece or rocking lever 9, is provided having tongues 10, extending laterally from each side thereof to lie in slots cut in the flanged portions '4, and also bearing against the ends of the plates 6, of the resilient base plate, permitting said levers, one being provided at each end of the device, to rock about the tongues as a pivot point. -However, in

order to relieve the small tongues 10, of the stress exerted upon the-mechanism when the fingerpiece is depressed to' elevate the toggle plates, said finger pieces are each-pro- Yided with adownstruck rounded portion 11, which is curvedand normallyrests upon the bottom of the base plate, so that the 7 fently of the other, a finger piece9, being pro- I vided at each end of the mechanism, one for each of said sets of'rings', so-that in openthe 'ring sections 8,

efl'ort exerted against the toggle plate in springing the same upwardly is transmitted through the actuatinglever to the .baseof the resilient plate and not through the i tongues 10. y y

In order to conceal the operating mocha: nismsand assist in retaining said finger pieces 9 in position a cover plate 12-.is.

flanged at its margins togfit over and around the flanged portions 4, of theba'se plate 3, and is slotted to permit freeimovemen't of said slots.

The operation is followsz'As already pointedout in the description there are tWo sets of ringsections', each operable .-independing-the rings for theinsertion or removal of and theprop'er operations proceeded with,

then the rings closed and the other sets of a page, one set ofrings may be first opened rings opened. This is particularly advan- I i .tageous in books attimes when the same are filled practically totheir full capacity with 7 pages, for the reason that where all of the rings'are opened-simultaneously, often times v anumber of the pages spring upwardly and are disengaged, thus inconveniencing the '40 user of the book. It-is a notable feature 01f the present invention that bolts, screws, or

other attaching means are entirely omitted,

all of theparts being rigidly associated with one another, due to the resiliency of certain of the members n U 1 I 1 In assembling the device the toggle plates 6, with the rings thereon are first fitted'be tween the inturned flanges 4, of the resilient base plate 3,, and-then by springing the base plate outwardly a slight amount suflicient space is afforded between the edges of the loosely, fitting toggle plates and the inner walls of .the inturned portions 4, of the base plate to permit the ready insertion of the leaf springs 5, the-respective pairs thereof,-

there' being four in all, bein g inserted at op-' posite ends of 'thebas'e plate. The actuating-" -'levers' or finger pieces' 9, -are next inserted with tlie tongues 10, thereof lying in the cut away or slotted portions'of'the flange merry.

bers 'l, of the base'plate,l'and finally the cover plate 12, is sprung over the folded por r-tions A, of the base plate, thus concealing the mechanisms therein'and assisting by 05.. means ofinbent' portions inxholding the which-extend through.

silient base plate having inwardly folded tongues 10 in their respective slots in operating position.

It is apparent that wide variations may be adapted to resiliently fit over and around the flanges of said base plate to conceal the operating mechanisms and retain the actuating means in position.
